STIRRUP.

SPECIFICATION forming part of Letters Patent No. 300,986, dated June 24,1884.

Application filed November 6, 1883. (No model.) Patented in Belgium September 30, 1882, No. 58,985; in France November 27, 1882 No.-150,937, and in Germany February 21, 1883, No. 21,106.

To all whom it may concern:

Be it known that I, FRITZ LEHMANN, of Tangerhiitte, near Magdeburg, in the Kingdom of Prussia and Empire of Germany, have invented certain new and useful Improvements in Stirrups, (which have been heretofore patented to me by the Government of Germany under date of February 21, 1883, N 0. 21,106; by the Government of 'Belgium under date of September 30, 1882, No. 58,985, and by the Government of France under date of N overnber 27, 1882, No. 150,937,) of which the fol lowing is a specification.

The object of my invention is to make a stirrup which will protect'the rider against being caught in the stirrup in falling and being dragged on the ground by the horse.

The invention consists in so arranging the stirrup that as soon as the riders foot is caught in it in falling it will become disengaged from the strap and from the foot by providing the stirrup with suitable releasing mechanisms, which will be fully described hereinafter.

I attain these objects by the arrangement illustrated in the accompanying drawings, in which similar letters refer to similar parts throughout the several views.

Figure 1 represents a front elevation of the stirrup when locked; Fig. 2, a top view with the eye for the strap in section; Fig. 3, a horizontal section on line 00 00, Fig. 1; Fig.4, a front elevation of the stirrup when released; Fig. 5,

a vertical transverse section on line y, Fig. 1; Fig. 6, a side view showing the foot in the act of releasing the stirrup, and Figs. 7 to 11 represent a modified construction of the invention.

The body of the stirrup, Figs. 1 and 2, is

formed of two symmetrical sections, D D,

which are hinged at the center point, m, of the stirrup-base F, and locked at the top by a pin, 6, passing into the overlapping parts E E at the upper ends of the stirrup-sections D D. Each half D of the stirrup carries onehalf of the eye for the strap, which halves are marked, respectively, n and a in the drawings. A strong spring, R, that is attached to the under side of the centrally-hinged basesections of the stirrup, forces the two halves of the stirrup apart at the moment when the pin 6 at the upper end of the face frame A releases the pin a. The face-frame A is made its end pins, 0, into corresponding holes in the base-plate.

Between the stirrupsections D D and the sides of the faceframe A are interposed Springs 8 s, which force the frame and stirrup apart until held by the stops 0 c,which are fastened to the sections D D, and fit into corresponding notches of the face-frame A. The

-pin 6 is firmly attached to the upper part of the facefra'me A, and fits into a hole in the plate E. of the plate E, and presses the pin 6 through the hole of the plate E, and far enough into the hole of the plate E to lock the two halves of the stirrup together. hen the pin 6 of frame A is pushed in, it forces the pin e back so that it releases the plate E, and the halves of the stirrup come apart. rup is in use, the face-frame A is held away from the body of the stirrup by the springs 88,. and thus the pin 6 is in a position which allows the spring 6 to force the pin 0 nearly through both plates E E at the upper part of the stirrup, thus holding the two sections a a of the strap-eye firmly together, as shown in Fig. 1. V hen pressure is applied to the face-frame A by the foot of the rider, as shown in Fig. 6, the pin 6, which projects back from the upper end of the same in the length of the hole of the plate E, forces back the pin 6 far enough to allow the two sections, D D, of the stirrup to separate through the action of the spring R at the base of the stirrup, where- 'by the eye a n will open, as shown in Fig. 4, and the stirrup be detached from the strap and dropped to the ground.

In the modification represented in Figs. 7 to 11 the stirrup D and the base-plate F form one piece, to which the spring-actuated faceframe A is connected, as before described. The strapeye 11 is made of a detachable piece, and so connected to the upper part of the stirrup D that when the face-frame A is pressed back by the foot of the rider the stirrup becomes detached from the strap-eye and in the shape of a horseshoe, and is inserted by The spring i is attached to the rear lVhen the stirdrops to the ground. The eye 22 has an enlarged shank, 7a, fitting into a corresponding vertical perforation or socket in the top of the stirrup. The pin 6, attached to the upper part of the face-frame A, passes horizontally through the top of the stirrup D, the perforation for the shank k partially intersects with the guide-hole of the pin 0, both the shank 7c and the pin cbeing recessed at points facing each other, so that when the face-frame A is in its normal position the shank 7c is rigidly locked by the pin 6, which passes through the recess of the shank; but when the pin 6 is pushed in, its notch will-be in line with that of the shank and allow the latter to be withdrawn. Thus, when, by the foot of the rider, the frame A is pressed in, the stirrup will detach itself from the eye an d drop to the ground. Having thus described my invention, I claim as new and desire to secure by Letters Patent 1. The combination of a stirrup, a springcushioned face-frameconnectedthereto,means, substantially as described, by which the stirrup is detachably connected to its strap, and means whereby the strap is released by the action of the face-frame and the stirrup dropped, substantially as set forth. 2. The combination of a stirrup having horizontal side stops, a springcushioned face frame connected thereto, means whereby the, stirrup is detachably connected to its strap, and means, substantially as described, secured to the face-frame, whereby the stirrup is disconnected from the strap when the face-frame is pushed toward the stirrup, substantially as specified.

3. The combination of the stirrup-sections D D, hinged together at their base and overlapping at the top, a strap-eye formed of overlapping parts at n at the spring-cushioned top of the stirrup, a spring-cushioned face-frame, A, connected to the base-plate of the stirrup and retained by side stops, 0 0, of the stirrup, a locking-pin, 0', passing through the overlapping top parts of the stirrup-sections, and a releasing-pin, c, at the upper end of the faceframe A, substantially as and for the purpose set forth.

4. The combination ofthe hinged and springactuated stirrup-sections D D, having fixed side stops, 0 c,,and overlapping top parts, E E, having overlapping parts an, forming the strap-eye, a spring-cushioned face-frame, A, having a releasing-pin, c, at its upper part, a locking-pin, 0, applied to a transverse spring, i, of the overlapping part E, said locking-pin being in line with the releasing-pin of the face-franie, so as to unlock the overlapping parts E E whenever the face-frame A is pressed back, substantially as described.

In testimony that I claimthe foregoing as my invention I have signed my name in presence of two subscribing witnesses.

FRITZ LEHMANN.
